Abstract: The cold water bleed propensity of acid and premetallized acid dyed cationic dyeable nylon fibers is substantially reduced by treating the fibers with both a nylon fixing agent and a cotton fixing agent. Colorfastness of acid and premetallized acid dyed nylon fibers, other than CD nylon fibers, is also enhanced by treating the fibers with both a cotton fixing agent and a nylon fixing agent.
Abstract: An electrorheological material comprising a carrier fluid and an atomically, polarizable particle component. The atomically polarizable particle component has a crystalline lattice structure which allows atoms to shift position with respect to each other in response to the application of an electric field. The electrorheological materials are subjected to an alternating current electric field at a frequency of at least 500 Hz. The materials exhibit substantial electrorheological activity over a broad temperature range.
Abstract: An improved sealant for sealing leaks in pipelines and refrigeration and air conditioning circuits includes a partially hydrolized tetra methoxy silane along with another organo silane sealant. The use of a partially hydrolized tetra alkoxy silane, such as partially hydrolized tetramethoxy silane, in place of an unhydrolized tetra alkoxy silane, gives a stronger and tougher and more elastic seal, and the partially hydrolized material is less toxic than the unhydrolized material.

Abstract: A detergent composition comprises a fired ceramic body, which carries as effective ingredients sodium oxide and potassium oxide thereon. Sodium metaphosphate and/or calcium oxide may also be carried as optional ingredient(s). The fired ceramic body may be made of a ceramic material formed primarily of silicon oxide and aluminum oxide. Preferably, the detergent composition may be in the form of granules and may be enclosed in a container defining apertures through a wall thereof. These apertures are dimensioned so that the granular detergent composition are prevented from being lost therethrough. A granular detergent composition can be produced, for example, by adding sodium oxide and potassium oxide to a ceramic material, adding water to the resulting dry ceramic powder, kneading and forming the resulting mixture into a green body of a predetermined shape, drying the green body, firing the thus-dried green body at 500.degree. C. to 700.degree. C.
